Gas production units are an essential component of the oil and gas industry, playing an essential role in the extraction, processing and transportation of natural gas. These units are used in the oil and gas industry to separate, process and prepare natural gas extracted from underground tanks, ensuring that it reaches consumers in high quality. Here we will go over everything you need to know about these units, including their function, how they work, and the benefits they provide.
How do gas production units work?
When natural gas is extracted from underground reservoirs, it often contains impurities and unwanted materials such as water, hydrocarbon liquids, and other gases, and this is where gas processing units come in to remove these unwanted components and prepare the gas for transportation and consumption. This treatment process takes place in several stages:
At this stage, the gas stream is passed through a primary separator where the bulk of the liquid hydrocarbons and water are removed and this is usually done using gravity or centrifugal force based separation methods.
-
Secondary separator
After primary separation, the gas stream is directed to a secondary separator to remove any liquids or solids remaining in the gas. This may involve the use of filters, combiners or vortex separators.
-
Gas drying
At this stage, water vapor is removed from the gas stream to prevent hydrate formation and corrosion in the pipelines. This can be achieved using different methods, such as glycol drying, solid desiccant or membrane-based drying.
-
Finally, gas purification
If natural gas contains significant amounts of acid gases, such as hydrogen sulfide (H2S) and carbon dioxide (CO2), it must be treated to remove these components. Gas purification processes, such as amine adsorption or extraction of unwanted gases with solids, are used to achieve this. Through these successive stages, you ensure the removal of impurities and unwanted materials from raw natural gas, and its preparation for transportation and final consumption with high quality.
Benefits of using gas production units
Gas production systems play a vital role in improving the efficiency and safety of natural gas extraction and distribution operations. This is done through a set of processes that purify the raw gas and prepare it for final use.
Gas processing units contribute significantly to raising the quality of the natural gas produced, as they remove impurities and foreign materials that may be present in the raw gas, such as water, sulfur, and liquid hydrocarbon compounds. This ensures that the gas produced meets stringent global standards necessary for safe transportation and distribution, and reduces the risk of corrosion and blockage in pipelines.
-
Environmental protection
By purifying the gas and removing harmful pollutants, gas processing units contribute to protecting the environment and reducing harmful gas emissions. This is crucial in light of global environmental challenges and growing interest in clean energy. In addition to reducing air pollution, these units help conserve natural resources and reduce the negative impact on biodiversity.
-
Increase economic efficiency
Gas production units contribute to achieving the maximum economic benefit from natural gas resources, as they work to increase the financial return from each gas unit extracted by reducing losses and improving gas quality. In addition, these units contribute to reducing operational and maintenance costs, and protect the environment by reducing harmful emissions.
-
Promoting occupational safety and health
Gas processing units play a crucial role in ensuring the safety of workers in the oil and gas industry, as they remove hazardous and toxic materials, such as hydrogen sulfide, which may pose a serious health threat. In addition, it also contributes to reducing the risk of fires and explosions that may occur as a result of gas leakage.
Locations of use of gas production units?
These units are widely used in the oil and gas industry including:
-
Gas production on land and at sea
Gas production systems are used in onshore and offshore natural gas production facilities to process the extracted gas before it is transported to the end user.
The units are often used in gas processing plants, where they perform crucial separation and treatment functions before the gas is processed or transported furthe
-
Wellhead
In some cases, gas production systems are used directly at the wellhead to process natural gas as it is extracted from the field, helping to reduce the need for additional infrastructure and transportation.
